Abstract

L'invention porte sur un procédé et un appareil de copie de données directement d'un support d'enregistrement vers des dispositifs portables d'enregistrement. L'appareil comporte un dispositif de copie comprenant un processeur, une mémoire, et une interface utilisateur. Le processeur est de préférence à double corps permettant de diviser les tâches et de les exécuter quasi simultanément. L'utilisation de l'appareil pour transférer des fichiers d'un support d'enregistrement vers des dispositifs portables permet un transfert plus rapide qu'aux vitesses de lecture en temps réel. Lorsque les fichiers enregistrés sur le support d'enregistrement sont des fichiers audio, l'appareil peut les transférer sur le dispositif portable, avec les informations sur les informations sur les pistes.
